Description

Technical Field

[0001] This utility model belongs to the field of grinding and pulverizing technology, and specifically relates to a grinding and pulverizing device for polyester resin. Background Technology

[0002] Crushing refers to applying external force to solid materials to break them into smaller particles. When crushing polyester resin, it is generally done by grinding with a crusher.

[0003] Traditional grinding and pulverizing equipment typically employs a fixed discharge structure with a single discharge direction. When the production line needs to adapt to different process flows (such as switching between continuous and intermittent production) or connect to multiple downstream devices (such as vibrating screens, packaging machines, and storage silos), manual handling of pipes, adjustments to equipment layout, or the addition of intermediate transfer silos are required, leading to increased production process complexity, material loss, and higher labor costs. Furthermore, in laboratory research and development or small-batch pilot production scenarios, a single discharge direction limits the equipment's compatibility with different collection containers (such as pallets, ton bags, and sealed tanks). Utility Model Content

[0004] The purpose of this invention is to provide a grinding and pulverizing device for polyester resin to solve the problem of the single discharge direction in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding and pulverizing device for polyester resin includes a pulverizer. A hopper is fixed at the bottom of the pulverizer. A feeding end is provided at one end of the feeding hopper. An inclined plate is provided at the bottom of the feeding hopper. A bottom feeding port is opened on the surface of the inclined plate. A front feeding port is provided on one side of the bottom feeding port in the vertical direction. A reversing mechanism is installed on the feeding end. The reversing mechanism is used to block the front feeding port or the bottom feeding port.

[0007] Preferably, guide surfaces are provided on both sides of the feeding end. The raw materials entering the feeding hopper slide down from the inclined plate to the feeding end, and the guide surfaces concentrate a large area of ​​material into the central area for discharge, which facilitates subsequent collection and processing of the material.

[0008] Preferably, a reinforcing block is provided at the bottom of the guide surface; the reversing mechanism includes a turn plate, a motor and a flap, a support plate is fixed on one side of the turn plate, the support plate cooperates with the reinforcing block, one side of the turn plate is parallel to one side of the reinforcing block, the other side of the turn plate is parallel to the guide surface, a motor is installed on one side of the turn plate, the output end of the motor is connected to a drive shaft, and a flap is fixedly connected to the drive shaft.

[0009] Preferably, a collection box is installed at the bottom of the discharge port, and a guide pipe is provided at the bottom of the collection box. The guide pipe faces opposite to the discharge end.

[0010] Preferably, the bottom of the feed tube has a downward-sloping corner in any direction. This downward-sloping corner is used to change the discharge direction of the feed tube. The downward slope is to facilitate the natural sliding of the raw material from inside the corner. Different slopes can be selected according to the actual usage.

[0011] Preferably, the corner is rotatably connected to the feed tube. This rotatable connection allows for easy and free adjustment of the angle, further enhancing the functionality of the invention.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] Example 1:

[0029] refer to Figures 1-6 A grinding and pulverizing device for polyester resin includes a pulverizer 10. A feeding hopper 20 is fixed at the bottom of the pulverizer 10. A feeding end 201 is provided at one end of the feeding hopper 20. An inclined plate 202 is provided at the bottom of the feeding hopper 20. A bottom feeding port 204 is opened on the surface of the inclined plate 202. A front feeding port 205 is provided on one side of the bottom feeding port 204 in the vertical direction.

[0030] The top of the crusher 10 is equipped with a feed hopper 11;

[0031] In the above scheme, polyester resin raw material is put into the feed hopper 11 and enters the crusher 10 for crushing. After being crushed by the crusher 10, the raw material falls into the feed hopper 20. The inclined plate 202 allows the crushed raw material to slide quickly off the surface of the inclined plate 202 and be discharged at the bottom feed port 204 or the front feed port 205. A container for receiving the raw material is placed below the bottom feed port 204 or the front feed port 205.

[0032] Further reference Figure 6The material discharge end 201 is provided with guide surfaces 203 on both sides. The raw material entering the hopper 20 slides down from the inclined plate 202 to the material discharge end 201. The guide surfaces 203 concentrate a large amount of material in the middle area for discharge, which facilitates the subsequent collection and processing of the material.

[0033] refer to Figures 3-8 A reversing mechanism is installed on the discharge end 201. The reversing mechanism is used to block the front discharge port 205 or the bottom discharge port 204.

[0034] The bottom of the guide surface 203 is provided with a reinforcing block 206; the reversing mechanism includes a crank plate 30, a motor 302 and a flap 304. A support plate 301 is fixed on one side of the crank plate 30. The support plate 301 cooperates with the reinforcing block 206. One side of the crank plate 30 is parallel to one side of the reinforcing block 206, and the other side of the crank plate 30 is parallel to the guide surface 203. A motor 302 is installed on one side of the crank plate 30. The output end of the motor 302 is connected to a drive shaft 303. A flap 304 is fixedly connected to the drive shaft 303.

[0035] In the above scheme, Figure 4 and Figure 5 In the image, the bold black line represents the location of flip panel 304. Figure 4 The middle flap 304 is located at the bottom feed inlet 204; Figure 5 The middle flap 304 is located at the front feed port 205; the square shape of the turn plate 30 can be parallel to the reinforcing block 206 and the guide surface 203, and combined with the support plate 301 and the top of the reinforcing block 206, it can achieve the initial positioning function and improve the installation efficiency of the motor 302.

[0036] Specifically, when the flap 304 is positioned at the bottom feed port 204, the bottom feed port 204 is in a closed state, and the raw material is discharged from the front feed port 205; when the flap 304 is positioned at the front feed port 205, the front feed port 205 is in a closed state, and the raw material is discharged from the bottom feed port 204.

[0037] Example 2:

[0038] refer to Figures 2-7 A collection box 40 is installed at the bottom of the bottom of the bottom feed port 204, and a guide pipe 401 is provided at the bottom of the collection box 40;

[0039] The orientation of the feed tube 401 is opposite to that of the discharge end 201.

[0040] In the above scheme, the raw material discharged from the bottom feed port 204 enters the collection box 40. The inner walls of the collection box 40 are inclined to the center of the guide pipe 401. The raw material passes through the collection box 40 and enters the guide pipe 401 for discharge. Since the discharge end 201 of the guide pipe 401 faces different directions, the discharge direction can be changed, so that the invention has discharge points in multiple directions. When different raw materials are changed for crushing, the flip plate 304 is rotated by starting the motor 302, thereby blocking the bottom feed port 204 or the front feed port 205, changing the discharge direction, collecting different raw materials, and making operation convenient.

[0041] It is worth noting that the motor 302 is controlled by a mechanical switch or a remote control switch. The mechanical switch needs to be installed on the outer wall of the crusher 10 or the outer wall of the hopper 20. The remote control can be carried at any time. The present invention does not disclose the control device in detail. Any switch that can control the start of the motor 302 can be used as the control device of the present invention.

[0042] Preferred Solution Reference Figure 9 The bottom of the feed tube 401 is provided with a downward-sloping corner 403 in any direction.

[0043] Here, the downward-sloping corner 403 can be used to change the discharge direction of the guide pipe 401. The purpose of the downward slope is to facilitate the natural sliding of the raw material from inside the corner 403. Different tilting corners 403 can be selected according to the actual use.

[0044] Further reference Figure 7 A connecting block 402 is installed on the feed pipe 401, and the top of the connecting block 402 is connected to the inclined plate 202. The connecting block 402 is used to reinforce the installation and positioning of the feed pipe 401.

[0045] Example 3:

[0046] refer to Figure 9 The corner 403 is rotatably connected to the guide tube 401. The rotatably connected corner 403 allows for easy and free adjustment of the angle, further improving the functionality of the invention.

[0047] The specific implementation process of this utility model is as follows:

[0048] The rotating flap 304 is controlled by starting the motor 302. When the flap 304 is in the position of the bottom feed port 204, the bottom feed port 204 is in a closed state, and the raw material is discharged from the front feed port 205. When the flap 304 is in the position of the front feed port 205, the front feed port 205 is in a closed state, and the raw material is discharged from the bottom feed port 204.

[0049] The raw material discharged from the bottom inlet 204 enters the collection box 40. The inner walls of the collection box 40 are inclined to the center of the guide pipe 401, so that the raw material passes through the collection box 40 and enters the guide pipe 401 for discharge.
